MOUNTING GUN-CARRIAGE s-PAnE's;

To all whom it may concern Be it known that'I, KARL VoLLER, engineer, a subject of the German Emperor, residing at 12 Scharnhorststrasse, Dusseldorf,

' Germany, have invented certain new and useful Improvements in the Mounting of Gun-Carriage Spades; and I do hereby declare the following to be a full, clear, and exact. description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to wheeled gun carriages and more particularly to the mounting of spades, which can be put in and out which can engage with the end of the limber of action as required, and in which a pressure plate is hinged to the spade and prevents the spade from penetrating too deeply into the ground. In previously known constructions of spades with hinged pressure plates several operationsare required to put the spade in and out of action and the manipulation in consequence is too complicated.

According to the present invention the operations of putting the spade in and out of 'gear are very much simplified by the arrangement in which the pressure plate is hinged to the spade, so that when the spade is moved the pressure plate is also moved.

A construction according to the invention is shown in the drawing, in which Figure 1 is a side view of the device in the working position, Fig. 2is a side view in the position, in which the pressure plate is automatically released from the limber eye when the spade is put out of action. Fig. 3 is a plan viewfrom above.

The spade a is hinged to the gun carriage 'b about the pin 0 so that in the work ing position it can be turned down, until it rests against the fixed spade d, and on the other hand can be turned over for the purpose of putting it out of'action, so as to lie' on the end of the trail in the position shown by the chain dotted lines in Fig.1. A pressure plate f is hinged by pins e to the spade a, and has on the under side a'hook 9,

eye it.

In the out of action position, the spade a and the pressure plate f lie on the rear end of the trail as shown by the chain dotted lines in Fig. l and are held in this position :Specification of Letters Patentl *fPatented'Aug 18, 1914:. Application filed August 2, 1913. Serial No. 782,667.

in transport by the lug z of the hand spike is which has been turned forward.

The lug z' presses against the blade of the spade in the dotted position and prevents both the spade a and the pressure plate from rising. If the gun is to'be fired with only the fixed spade (Z in use, the spade a and the pressure plate f are held in the dotted positions by'the projection on the hand spike.

The spade 'a and pressure plate f are changed over into the Working positions by turning thehand spike 70 out of the transport position in the direction shown by the arrow until the projection z releases the spade a. The spade a is then turnedover until it rests against the fixed spade d when the limber eye as the spade a is turned over 1n its position.

The change from the working effected by releasing the catch dle n and then turning back The pressure plate so far to the right Fig. 2), that the hook g is released from the limber eye it, whereupon the spade and pressure plate are turned together into the position shown dotted in Fig. 1 I i I claim as my invention:

1. A wheeled gun carriage having a spade capable of being moved into and out of op erative position, and a pressure plate hinged to said spade and movable therewith.

2. In combination with the trail of a wheeled gun carriage, a spade capable of being moved into and out of operative position, a pressure plate hinged to said spade and movable therewith, and a locking member on said pressure plate designedto engage the eye of said trail to hold said spade and plate in operative position.

8. In combination with the trail" of a wheeled gun carriage, a spade capable of being moved into and out of operative position, a pressure plate hinged to said spade and movable therewith, a catch for. holding said spade in operative position, and means on said tra l for holding said pressure plate against the spade d, fixing the pressure plate position is m by a hanthe spade a.
